NEET MCQ Books for XIth & XIIth Physics, Chemistry & Biology

Assertion: The velocity of a body at the bottom of an inclined plane of a given height is more when it slides down the plane, compared to when it is rolling down the same plane.
Reason: In rolling down, a body acquires both kinetic energy of translation and rotation.
1. Both assertion and reason are true and the reason is the correct explanation of the assertion.
2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is true but the reason is false.
4. Both assertion and reason are false.

NEET MCQ Books for XIth & XIIth Physics, Chemistry & Biology

Assertion: Two cylinders, one hollow (metal) and the other solid (wood) with the same mass and identical dimensions are simultaneously allowed to roll without slipping on an inclined plane from the same height. The solid cylinder will reach the bottom of the inclined plane first.
Reason: By the principle of conservation of energy, the total kinetic energies of both the cylinders are equal when they reach the bottom of the incline.
 
1. Both assertion and reason are true and reason is correct explanation of assertion.
2. Both assertion and reason are true but reason is not the correct explanation of assertion.
3. Assertion is true but reason is false.
4. Both assertion and reason are false.
